Cloud Computing is a key component as businesses worldwide go through a dynamic shift to a holistic end-to-end digital transformation. Cloud Computing has altered the way people create, operate, and use software products and services.
As cloud computing becomes the norm and its usage becomes vast, it is pertinent to understand the different types of cloud computing and characteristics of cloud computing. For facilitating the migration to the cloud dependent on specific requirements whether it is for businesses or independent developers.
What is Cloud Computing?
Cloud computing is the on-demand access to computing resources—applications, servers (physical and virtual), data storage, development tools, networking capabilities, and more—hosted at a remote data centre managed by a cloud services provider via the internet (or CSP). The CSP makes these resources available for a monthly subscription fee or charges a usage fee.
Cloud computing as a term was inspired by the cloud symbol, which is frequently used in flowcharts and diagrams to represent the internet.
The hardware and software components required for the proper implementation of a cloud computing model are referred to as cloud infrastructure in an all-encompassing manner.
Fundamentally, cloud computing is a catch-all term for anything involving the delivery of hosted services over the internet. These services are classified into three types: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Here’s the best cloud computing language for every developer.
5 Main Types of cloud computing
Now that we have learned what is cloud computing. Let’s understand the major types of cloud computing in trend. There are four main types of cloud computing: private clouds, public clouds, hybrid clouds, and multiclouds. Choosing a type cloud service is a unique decision and is very crucial. So let’s dive deep into the different types of cloud computing in detail.
Among the different types of cloud computing models, we will first discuss the private cloud model. The public cloud refers to a set of computing services provided over the internet by third-party providers, offering a broad range of services that can be purchased or used by anyone interested. Users can access public clouds for free or on-demand, paying only for the computing resources used, such as CPU cycles, storage, or bandwidth.
Using public clouds can help businesses save money by eliminating the need to purchase, manage, and maintain on-premises infrastructure, as the cloud service provider takes care of system management. Public clouds also provide scalability and flexible bandwidth and RAM, enabling businesses to easily expand their storage to meet their needs.
Private clouds are a pool of computing resources that are provided over a private network of computers and exclusively used by a single organization over a prolonged period. This cloud is also known as an internal cloud, enterprise cloud, or corporate cloud. A private types of cloud computing is usually managed by internal resources and its use is restricted to the organization. There are various advantages to using a private cloud, such as self-service, scalability, elasticity, and additional controls, security, and customization.
Private clouds offer a higher level of security by encrypting sensitive data and hosting it internally, preventing third-party access to sensitive information. However, private clouds also have a major disadvantage, which is the organization's responsibility to manage and maintain all the data centers themselves, leading to considerable resource consumption.
Hybrid clouds combine the benefits of both public and private clouds, offering the "best of both worlds" approach to cloud computing. This type of cloud computing allows businesses to shift workloads between public and private clouds, depending on computing requirements and cost. As a result, organizations can scale their on-premises infrastructure up to the public cloud when the demand for computing and processing fluctuates. This enables them to handle any overflow without worrying about their data being accessible to third parties and ensures their data is protected from third-party access.
Community Cloud is a types of cloud computing approach where infrastructure is shared among organizations that have common interests, such as security or compliance requirements. This type of cloud can be considered a hybrid of private and public clouds, but it's only accessible to a group of organizations that share the same community cloud infrastructure. In this model, organizations share resources, costs, and responsibilities, which can result in significant cost savings and increased efficiency.
Community Clouds are typically used by organizations with shared concerns around data privacy, security, and regulatory compliance. It allows multiple organizations to share the same cloud infrastructure, while maintaining control over their own data and applications. This model is often used by government agencies, healthcare providers, and financial institutions.
Multi-cloud is one of the best types of cloud computing models, which refers to an approach where organizations use multiple cloud services from different cloud vendors, be it private or public clouds. While a hybrid cloud can also use a multi-cloud approach, not all multi-clouds are hybrid clouds. A hybrid cloud is created by integrating multiple clouds or orchestrating them to form one unified cloud.
Multi-cloud environments may be designed intentionally for better data control or as an additional layer of disaster recovery, or they may occur accidentally, usually as a result of shadow IT. Regardless, many organizations are adopting multi-cloud strategies to enhance security and performance by leveraging various platforms.
High-performance Computing (HPC) cloud
High-performance Computing (HPC) cloud is a cloud computing model that provides high-performance computing services to perform advanced computing tasks that require significant processing power, memory, and storage capacity. It enables users to run complex, data-intensive applications on virtual machines, and provides access to a large number of processors, memory, and storage resources.
Difference in the Types of Cloud Computing
The differences between cloud computing models appear in terms of ownership, accessibility, security, cost, scalability, flexibility and maintenance, and these can be seen as advantages & disadvantages of cloud computing
|Aspect||Public Cloud||Private Cloud||Hybrid Cloud||Multi-Cloud||Community Cloud|
|Ownership||Owned and operated by a cloud service provider||Owned and operated by an organization||Combination of public and private clouds||Multiple clouds from different providers||Shared by multiple organizations with similar needs|
|Access||Available to anyone with internet access||Restricted access within the organization||Access to both public and private cloud resources||Access to multiple clouds from different providers||Shared access by multiple organizations|
|Security||Security is the responsibility of the cloud service provider||Security is the responsibility of the organization||Security is a joint responsibility between the organization and the cloud service provider||Security is the responsibility of each cloud service provider||Security is shared among the community members|
|Cost||Pay-as-you-go model based on usage||Higher upfront costs and ongoing maintenance expenses||Combination of pay-as-you-go and upfront costs||Combination of pay-as-you-go and upfront costs||Cost sharing among community members|
|Scalability||Highly scalable and can accommodate varying workloads||Scalability depends on the infrastructure capacity of the organization||Scalability depends on the combination of public and private clouds||Scalability depends on the combination of multiple clouds||Scalability depends on the community's needs|

Similarities in the Types of Cloud Computing
All of the above types of cloud computing, offer service models such as IaaS, PaaS, and SaaS. They all feature shared infrastructure in terms of resource pooling, high scalability, on-demand self-service, high availability, virtualization technology, data protection, and centralized management.
All types of cloud computing have highly scalable resources that can be accessed through on-demand self-service, making them convenient and efficient for users. They all employ virtualization technology, allowing multiple users to share the same infrastructure while maintaining data protection and centralized management. Additionally, all cloud computing models provide a high level of availability to ensure that services remain accessible to users.
Overall, despite their differences, all types of cloud computing offer similar features and benefits. Benefits of cloud computing in data science & MI can help make informed decisions.
